Hi!
I am planning to test a service for availability and if the service is
not available anymore, fence the node and start the service on another
node. Therefore, i need a clue how to probe a port with system tools.
Sure, with telnet there is a possibility to check. But i have no idea
to avoid the interactivity. So it is too difficult for me to implement
and usually not allowed in this environment.
On Solaris, there is the "ping -p" command to test the availability of
a application waiting on a port. But for Redhat, i have no clue.
Could you please help?
Peter
